Sensomatic - a possible low cost microbiology sensor/controller board

[Jonathan Cline]

Microbiology Sensor/Controller Board: The Sensomatic

I gave a short presentation at the Carlsbad bio-incubator tonight that was well received.  This project proposal is based on a separate DIYBio presentation and later discussions with Cory Tobin of LA Biohackers.  The goal of the sensomatic project is to create a tool which eliminates the bring-up hassles of many microbio projects (culturing related).   Cory's real (i.e. perhaps to be published) bio project is used as a proxy for requirements generation of the Sensomatic.  Along with the requirements:  simplicity, low cost, and built to solve a specific problem.

Comments are welcome especially regarding similar controllers already out there for comparison to this possible project.

Cheapstat exists. It's a potentiostat board. Probably over $100 once you add sensors, and mostly
intended for electrode voltage studies. Programmed in Java. Your UBW and YAML driven method seems better.

Really it is only the PC side code that is Java. Not sure what the AVR firmware is done with.

Your UBW and YAML driven method seems better.

A version of this with the firmware only about taking a quick accurate analog reading,
and leaving the cycling timings in YAML might be an improvement.
